UITableView add row below selected row - iphone

Question

I had a working tableview where I could double-tap a cell and it would add an 'action' cell below which had four buttons programmed on it.
Today I added alphabetic sections to the tableview and a section index and I can no longer get this functionality to work.
I've added a whole range of NSLogs to the code to try and find the problem and I can't, it seems to be trying to add a row in the same section and one row further down than the cell tapped, so I'm not sure what the problem is. Would anyone have any idea what I'm doing wrong?
If anyone can shed any light on this I would be hugely appreciative. (And apologies if my code is cumbersome or hard to follow, I'm new to this so feel free to suggest what I can improve!)

}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView

return [nameIndex count];

if (self.actionRowIndexPath) {
//Returns first letter of the section
NSString *alphabet = [nameIndex objectAtIndex:section];
//Returns the number of entries starting with that letter

int intNumberOfRows = ([numberofRows integerValue] + 1);
return intNumberOfRows;

NSString *alphabet = [nameIndex objectAtIndex:section];
NSString *numberofRows = [nameIndexCount objectForKey:alphabet];

After you get the IndexPath you need to get the IndexPath.row and IndexPath.section and accordingly you need to add the object into your array at the desired index. For example: if you double tap the 2nd row in the 1st section then you need to add the object at index 4 of the array corresponding to the 1st section and then reload table. The cell would be added to the 3rd index of the 1st section.
